Sleep and indoor air quality: an exploratory polysomnographic evaluation of pot...

This exploratory pilot study examines the potential impact of indoor environmental exposures on sleep quality, with a particular focus on a comprehensive characterization of indoor air quality (IAQ) parameters and their association with sleep architecture assessed through polysomnography. The study was conducted during the cold seasons of 2016 and 2017 with a small sample of 10 subjects from the urban area of L...

Strawberry plant as a biomonitor of trace metal air pollution: a citizen scienc...

A biomonitoring study of air pollution was developed in an urban-industrial area (Seixal, Portugal) using leaves of strawberry plants (Fragaria × ananassa Duchesne ex Rozier) as biomonitors to identify the main sources and hotspots of air pollution in the study area. The distribution of exposed strawberry plants in the area was based on a citizen science approach, where residents were invited to have the plants...

Self-perception of sleep quality and indoor air quality: preliminary findings f...

Sleep plays an important role in essential body functions, individuals’ welfare, health, and daily productivity. Sleep structure is vulnerable to several features that include both pathophysiology processes and environmental influences. Typically, sleeping environments are characterized by low ventilation rates, leading to pollutant accumulation. Adding to this, the breathing zone is very close to potential sou...

Self-perception of indoor air quality during sleep: preliminary findings from H...

Introduction: Building occupants' comfort and health have been enhanced by Indoor Air Quality (IAQ). This concept has drawn increased attention in recent decades from the international scientific community, political institutions, and environmental governance. Additionally, the traditional methods for assessing indoor air quality(IAQ)are intended to reduce and control indoor air pollutants without considering t...

Insomnia and sleep apnea: would indoor environment change the picture?

Introduction: Sleep is essential for overall health and well-being, impacting several dimensions from cognitive impairment to cardiometabolic risk. Yet, many individuals struggle with sleep-related issues such as sleep apnea, and insomnia, often without realizing that the indoor environment may be a contributing factor. The present data concerns the preliminary results from one of the tasks of the HypnosAirStud...

Microplastic contamination of lettuces grown in urban vegetable gardens in Lisb...

Urban vegetable gardens are very often a feature of cities that want to offer their citizens a more sustainable lifestyle by producing their own food products. However, cities can have significant pollution levels (or pollution hotspots) due to specific sources of pollution, such as traffic. Among the various pollutants, microplastics (MPs) are emerging as a consensual concern due to the awareness of the enviro...

Source apportionment of PM2.5 before and after COVID-19 lockdown in an urban-in...

The lockdowns held due to the COVID-19 pandemic conducted to changes in air quality. This study aimed to understand the variability of PM2.5 levels and composition in an urban-industrial area of the Lisbon Metropolitan Area and to identify the contribution of the different sources. The composition of PM2.5 was assessed for 24 elements (by PIXE), secondary inorganic ions and black carbon. The PM2.5 mean concentr...

Citizens’ perception on air quality in Portugal: how concern motivates awareness

This study aimed to understand the knowledge of Portuguese citizens about air quality and the extent to which the concerns about specific environmental problems can motivate their acquaintance of information. Moreover, this study also allowed to understand which information about air quality needs further dissemination to provide the citizens with all the available tools and the correct knowledge. For this, a n...
